Ultrasound measurement method of blood flow in heart valve, involves evaluating measurement and reference beams overlapping measurement areas covering orifice, to determine volumetric flow rate and flow volume of blood

摘要

The measurement beams (7) and reference beams (8) overlapping measurement areas (9,10) covering an orifice (2), are evaluated to determine volumetric flow rate and flow volume of the blood through orifice. An independent claim is also included for ultrasound measurement device of blood flow.
